BILGE PUMP:

.Ap1.v1ica:ioir'led October 1, 1921. Serial'No. 504,585.v

ToaZZ whom. t may concern:

Be. itknow-n that'I, HENRY HANsoN, a citizen of the United States,residing at Middletown, v4in the countyof Middlesex and 5f State ofConnecticut, have invented'certain' new' andy useful` Improvements inlBilge Pumps, of which thefollowing'is af speci lication, reference beinghad thereinito the accompanying drawings.

f This :invention relates to new and useful improvementsvin bilge pumps.

It is the'object of the invention,'among other things, to -provide apump of thischaracter'that may be readily connected with anddisconnected from the. propeller or other driving s haft, whereby thepump may be OperatedA at willi and from any part ofthe vessel, and tovproduce ay selfcontained mechanism that may be set up and taken downzasa unit.r

. Among other arrangements andobjects .of

theinvention may be recitedAthe-provision of a device of thecharactermentioned, with a View to fcompactness, in which the number yofparts-"are few, the construction simple, the

costi` off production small, and efliciency and operation high.

Tof these, and other ends, my invention consists inthe bilge pumphaving-certain de- ,30' tails of construction and combinations ofparts-faswill be hereinafter described .and moreparticularly pointed outin the claims. Referring to the drawings, wherein like referencecharacters' designate-like parts in i the several' figures Figure 1 isaside elevation'fof my iinproved bilge pump with thepropeller'shaft insection and a driving gear thereon.

` Figure 2 ris a plan view thereof, the parts- 40' in section being uponline; 2 2 of Figure y1;

Figure 3 is a sectional elevation of the cylinderk and the laterallyprojecting lug and ball valves, taken generally upon line 3-3 of Figure2; and

Figure 4 is aftransverse 'section' of the shaft, takenigenerally uponline 4 4 of'Figure 2.

' Bilgeipumps generally are ycontinuously operated from thepropellershaft. 1t is not 0 necessary and in fact is not desirable thatthe bilge pump should operate during all of the time that the vpropellershaft is rotating. Means havefbeen provided, however, for disconnectingthe bilge pumps from the propel; ler. shaft but have generally been sodesigned as `to be more or less --complicated iii'A opera-Ltion,.imposs1ble of operation under some conditions, frequently requirethe stopping member, reinforced by the rib 44and upon whichare'thestandards 11-11 at one end andthestandards 12-12 at'the opposite end.Secured to the top of the latter standards, bythe screw 14 orsimilarmeans,- is the cylinder-lfhaving one closedend, and adjacent` theretothe radially projecting lugs 15 which are interiorly threaded at 16 withball valves 17 of conventional form connected therewith. The cylinder isdrained ofaccumulated water therein, when? desired, through an aperturein the underside of the rear end thereof,l normally closed by the plug48.

yA plunger' 18 is-movable Within the cylinderand upon'the outer end ofwhich is threaded a nut'19 containing a gasket. or packing, as may bemost suitable.

Journaled within the standards 11y is a shaft 20 having thereon aneccentric collar 21, upon which is rotatably mounted the -gear 22 andaneccentric collar 23. This gear and vents endwise movement ofthe gear 22and eccentric collar 23 thereon, and a pin 26 that passes therethrough,through the collar 21 and the shaft 2() provides convenient means forsecuring the eccentric collar 21, shaft 20 and the collar 25.

Encircling the eccentric collar 21 is the eccentric strap 27 which issplit at 28, and by means of the screw 29 and nut 30 it may be held inproper frictional relation to said collar. This strap has a hingedconnection with the plunger 18 through the pin 31. yA stop pin 32 thatprojects radially upon opposite sides of the shaft 20, contacts with afixed stop 33 connected with one of the standards 11 to limit themovement of the shaft about its axis.

Rotation is imparted to the shaft 20 through the gear sector 34,journaled at 35, and having an arm 36 connected therewith, the teeth `ofwhich mesh into those on the sector 37 that is adjustably andfrictionally secured to the shaft 20 by means of the screw 33 connectedwith the integral ears 39. Any one of many other convenient means may besubstituted for securing this sector, but it is desirable that it be soconnected with the shaft as to be moved into various positions about theaxis thereof, thereby accommodating the sector 34, which may, by reasonof the construction of the vessel to which the )ump is connected, occupya different anglle to the base member i() than that shown herein.

The propeller or other shaft from which the source of power is obtainedto operate the bilge pump is designated 40, and connected therewith is agear 41.

In Figure 1th@ pump is shown with the teeth of the gear 22 in mesh withthose of the gear 41, at which time the plunger 18 of the pump isreciprocating within the cylinder 13, and the stop pin 32 is in contactwith the fixed stop 33 in substantially the position shown by full linesin Figure 4.

If it is desired to stop the bilge pump, the arm 36 is manipulated so asto roclr the sector 34 upon its pivot mounting, thereby impartingrotation to the shaft 20 and all mechanisms connected therewith. Thismovement of the shaft 20 causes the eccentric collar 21 to travel aboutthe axis of the shaft, and by reason thereof, the position of the gear22 and eccentric collar 23 is shifted sufficiently` to disengage theteeth of the gear 22 from those of the gear 41 and thus separate thepump from its source of power. The pump parts now come to their restposition. at which time the stop pin 32 is againstwthe fixed stop 33 insubstantially the position shown by the broken lines in Figure 4.

The arm 36, the upper end of which is shown broken ofi', may be operatedeither b y grasping the same or from any other por* tion of the boat byconnecting it with a rope or in any other convenient manner well knownin the art. The pump may thereby be set in motion or stopped from anypart of the vessel. As all of the mechanisms are connected with the basemember 10, the pump is assembled as a unit and secured by means 'ofbolts or screws passing through the openings 42 therein. The ball valvesand connections being integral with the cylinder it is merely necessaryto thread a pipe in the end of each and the pump is ready for operation.

There are minor changes and alterations that may be made within myinvention, aside from those herein suggested, and I would therefore haveit `understood that I do not limit myself to the exact constructionherein shown and described, but claim all that falls fairly within thespirit and scope of the appended claims.v
